What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 4 of its 4 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Tricycline contains four ingredients. The two we have data on are black walnut and berberine sulfate (an alkaloid extracted from plants like goldenseal and barberry).

The product also includes artemisinin and citrus seed extract, which we could not check for interactions. Three inactive ingredients—hydroxypropyl methylcellulose, microcrystalline cellulose, and L-leucine—are added as fillers and capsule material.

Does it work?

Moderate evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: GI balance and digestive health support.
  • We looked for evidence on: Diarrhea, Helicobacter pylori, Irritable bowel syndrome (IBS), Ulcerative colitis, Cholera, Intestinal parasites — and 2 related terms.
  • The strongest evidence on file: Berberine is rated "Possibly Effective" for Helicobacter pylori (Natural Medicines).
  • Also on file: Berberine is rated "Insufficient Reliable Evidence To Rate" for Cholera, Radiation-induced diarrhea, Ulcerative colitis, Irritable bowel syndrome (IBS).

Berberine has been rated Possibly Effective for high cholesterol (hyperlipidemia), high blood pressure (hypertension), diabetes, polycystic ovary syndrome (PCOS), and Helicobacter pylori infection based on available research. Black walnut has been rated Insufficient Reliable Evidence To Rate for both coronary heart disease and wound healing—meaning the research to date doesn't establish whether it works for these uses.

We hold no effectiveness data for artemisinin and citrus seed extract in our records.

The evidence, ingredient by ingredient Black Walnut Berberine Sweet Annie

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Black walnut is generally well tolerated when the fruit (nut) itself is used, but the leaf, bark, and hull contain high amounts of tannins and may cause stomach upset and, on the skin, irritation or temporary yellow or brown staining. Tree nuts can trigger allergic reactions in sensitive people.

Long-term safety data are limited. Berberine is generally well tolerated short-term but commonly causes digestive side effects—abdominal pain, diarrhea, constipation, nausea, or flatulence.

It can also cause dizziness, drowsiness, or headache. For pregnancy: black walnut is not recommended (not enough safety information), and berberine should be avoided (it may cross the placenta and harm the developing baby).

For breastfeeding: black walnut should be avoided, and berberine should not be used because it passes into breast milk.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Tricycline may be worth considering if you're exploring herbal support for blood sugar or cholesterol, but berberine's broad medication interactions make it essential to check your exact prescriptions first—especially blood thinners, blood pressure drugs, diabetes medications, and cyclosporine. Avoid it in pregnancy and while breastfeeding.

Talk with your pharmacist or doctor before starting, particularly if you take any regular medications.

Each ingredient & the kinds of drugs it affects

For each ingredient in Tricycline with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Berberine Sulfate15 drug types · 1,160 drugs

Cyclosporine (Neoral, Sandimmune)

Berberine can increase serum levels of cyclosporine.
Berberine can reduce metabolism and increase serum levels of cyclosporine. Berberine might inhibit cytochrome P450 3A4 (CYP3A4), which metabolizes cyclosporine.

Likelihood Probable Evidence A
Anticoagulant/Antiplatelet Drugs

Theoretically, berberine might increase the risk of bleeding when used with anticoagulant or antiplatelet drugs.
In vitro and in vivo research suggest that berberine can inhibit platelet aggregation. Theoretically, berberine might have additive effects when used with anticoagulant and antiplatelet drugs and increase the risk of bleeding.

Likelihood Possible Evidence D
Antidiabetes Drugs

Theoretically, berberine may increase the risk of hypoglycemia when taken with antidiabetes drugs.
Clinical research shows that berberine may lower blood glucose levels. Theoretically, berberine might have additive effects with antidiabetes drugs and increase the risk of hypoglycemia.

Likelihood Possible Evidence D
Antihypertensive Drugs

Theoretically, berberine might have additive effects with antihypertensive drugs.
Animal research suggests that berberine can have hypotensive effects. Also, a clinical study suggests that taking berberine in combination with amlodipine can lower systolic and diastolic blood pressure when compared with amlodipine alone.

Likelihood Possible Evidence D
Cns Depressants

Theoretically, berberine might increase the sedative effects of CNS depressants.
Animal research suggests that berberine may have sedative effects. Theoretically, use of berberine along with CNS depressants might produce additive therapeutic and adverse effects.

Likelihood Possible Evidence D
Cytochrome P450 2C9 (Cyp2C9) Substrates

Theoretically, berberine might increase serum levels of drugs metabolized by CYP2C9.
Preliminary clinical research shows that berberine can inhibit CYP2C9. Theoretically, taking berberine with drugs metabolized by CYP2C9 might increase drug levels and increase the risk of adverse effects.

Likelihood Possible Evidence B
Cytochrome P450 2D6 (Cyp2D6) Substrates

Theoretically, berberine might increase serum levels of drugs metabolized by CYP2D6.
In vitro research and preliminary clinical evidence show that berberine can inhibit CYP2D6. Theoretically, use of berberine with drugs metabolized by CYP2D6 might increase drug levels and increase the risk of adverse effects.

Likelihood Possible Evidence B
Cytochrome P450 3A4 (Cyp3A4) Substrates

Theoretically, berberine might increase serum levels of drugs metabolized by CYP3A4.
In vitro research and preliminary clinical research show that berberine moderately inhibits CYP3A4. Theoretically, use of berberine with drugs metabolized by CYP3A4 might increase drug levels and increase the risk of adverse effects.

Likelihood Possible Evidence A
Dextromethorphan (Robitussin Dm, Others)

Theoretically, berberine may increase serum levels of dextromethorphan.
Preliminary clinical research shows that berberine can inhibit cytochrome P450 2D6 (CYP2D6) activity and reduce the metabolism of dextromethorphan. This may increase the effects and side effects of dextromethorphan.

Likelihood Possible Evidence B
Losartan (Cozaar)

Berberine might reduce the therapeutic effects of losartan by decreasing its conversion to its active form.
Preliminary clinical research suggests that berberine can inhibit cytochrome P450 2C9 (CYP2C9) activity and reduce metabolism of losartan.

Likelihood Possible Evidence B
Metformin (Glucophage)

Theoretically, berberine might increase the therapeutic and adverse effects of metformin.
In vitro and animal studies show that berberine can increase the systemic exposure and half-life of metformin, potentially increasing metformin's effects and side effects. This interaction seems to be most apparent when berberine is administered 2 hours prior to metformin. Taking berberine and metformin at the same time does not appear to increase systemic exposure to metformin.

Likelihood Possible Evidence D
Midazolam (Versed)

Berberine can reduce metabolism of midazolam, which might increase the risk of severe adverse effects.
Preliminary clinical research shows that berberine can inhibit cytochrome P450 3A4 (CYP3A4) activity and reduce metabolism of midazolam.

Likelihood Possible Evidence B
Pentobarbital (Nembutal)

Berberine might increase the sedative effect of pentobarbital.
Evidence from animal research shows that berberine can prolong pentobarbital-induced sleeping time. Theoretically, combining berberine and pentobarbital might increase the sedative effects of pentobarbital.

Likelihood Possible Evidence D
Tacrolimus (Prograf)

Berberine has been associated with increased blood levels of tacrolimus.
In a 16-year-old patient with idiopathic nephrotic syndrome who was being treated with tacrolimus 6.5 mg twice daily, intake of berberine 200 mg three times daily increased the blood concentration of tacrolimus from 8 to 22 ng/mL. Following a reduction of the tacrolimus dose to 3 mg daily, blood levels of tacrolimus decreased to 12 ng/mL.

Likelihood Possible Evidence D
Acetazolamide

Laboratory studies and initial clinical findings suggest that berberine has the potential to increase acetazolamide concentrations in the body. More research is needed to confirm this interaction.

Likelihood Possible Evidence C
Berberine Sulfate full monograph & interactions

Artemisinin3 drug types · 889 drugs

Cytochrome P450 2B6 (Cyp2B6) Substrates

Sweet Annie may alter plasma levels and clinical effects of drugs metabolized by CYP2B6.
In vitro research shows that the Sweet Annie constituent artemisinin induces CYP2B6, possibly increasing CYP2B6 activity by 1.6-fold. However, Sweet Annie extract seems to inhibit the activity of CYP2B6 in vitro, suggesting that other constituents of Sweet Annie play a role in its effects on the overall activity of this enzyme. More information is needed to determine whether taking Sweet Annie extract affects the metabolism of CYP2B6 substrates.

Likelihood Possible Evidence D
Cytochrome P450 3A4 (Cyp3A4) Substrates

Sweet Annie may alter plasma levels and clinical effects of drugs metabolized by CYP3A4.
In vitro research shows that the Sweet Annie constituent artemisinin induces CYP3A4, possibly increasing CYP3A4 activity by 1.9-fold. However, Sweet Annie extract seems to inhibit the activity of CYP3A4 in vitro, suggesting that other constituents of Sweet Annie play a role in its effects on the overall activity of this enzyme. More information is needed to determine whether taking Sweet Annie extract affects the metabolism of CYP3A4 substrates.

Likelihood Possible Evidence D
Hepatotoxic Drugs

Theoretically, concomitant use might have additive adverse hepatotoxic effects.
There is some concern that Sweet Annie can adversely affect the liver.

Tricycline by Allergy Research Group: Common Questions

Does Tricycline by Allergy Research Group interact with any medications?
Yes. Based on its ingredients, Tricycline has a known interaction with 1,325 medications, including 1 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Tricycline contains 4 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What is berberine, and what is it supposed to do?
Berberine is an alkaloid (a plant-derived compound) that research suggests may help with high cholesterol, high blood pressure, diabetes, PCOS, and Helicobacter pylori infection. It's been rated Possibly Effective for these uses, meaning the evidence supports a potential benefit, though more research may still be needed.
Can I take this if I'm pregnant or breastfeeding?
No. Berberine should be avoided during pregnancy—it may cross the placenta and has been linked to harm in newborns—and while breastfeeding because it enters breast milk. Black walnut is also not recommended in either situation due to insufficient safety data. Talk with your obstetrician or midwife before using any supplement in pregnancy or lactation.
What side effects might I experience?
Berberine most commonly causes digestive upset—stomach pain, diarrhea or constipation, gas, nausea, or vomiting. It can also cause dizziness, drowsiness, fatigue, or headache. Black walnut may cause stomach upset; if applied to skin, it can cause irritation or temporary yellowing or browning. Tree nuts can trigger allergic reactions in sensitive individuals.
Does black walnut interact with medications?
We have no documented interactions on file for black walnut. That doesn't mean none exist, but the data we hold show no known medication interactions for this ingredient.
Why do I need to check so many medications with this product?
Berberine affects three major liver enzymes that break down a very large number of prescription and over-the-counter drugs. Even if a medication isn't on a specific 'interaction list,' it may be metabolized by one of these pathways, and berberine could raise its level in your blood. That's why checking your exact medications—not just drug types—is important.
Is this product safe to use long-term?
Black walnut's long-term safety hasn't been well studied in humans. Berberine has been used short-term in research with generally good tolerability, but we don't have strong long-term safety data either. Talk with your pharmacist about how long you plan to take it and whether periodic check-ins make sense for you.
